If there's one thing several people are really, really good at, it's ruining the web. The latest attempt is something quite insipid, something that had me scratching my head a few times before I realised what was going on. When copying and pasting text from certain websites, content would be added to your clipboard without you knowing about it - something like "Read more at". John Gruber finds this just as insipid as I do, and investigated a little further - while also coming up with a way to block this nonsense. Seriously - this is right up there with those in-text underline ad things.
